EKG Testing

An electrocardiogram — abbreviated as EKG or ECG — is a test that measures the electrical activity of the heart. It shows the heart's electrical activity as line tracings on paper. This non-invasive procedure provides two major kinds of information to your doctor. First, by measuring time intervals on the EKG, a doctor can determine how long the electrical wave takes to pass through the heart, thus showing if the electrical activity is normal or slow, fast or irregular. Second, by measuring the amount of electrical activity passing through the heart muscle, a doctor may be able to find out if parts of the heart are too large or are overworked.

Hearing Screening

At NMA, we use a screening instrument called an EroScan that measures Otoacoustic Emissions (OAE) in our patients. Otoacoustic emissions are sounds that are produced by the cochlea (outer hair cells) and can be measured in the ear canal. When sound passing through the ear canal reaches the cochlea, the vibration stimulates thousands of tiny hair cells. This creates a byproduct that can be detected and measured: otoacoustic emissions. Testing takes less than 30 seconds per ear, and since no response is required from the patient, the test is completely objective, and can be performed on any age group. This screening tool provides us with a quick and accurate reading letting us know if a patient passes or needs to be referred to an Audiologist.

Anticoagulation Testing

Anticoagulation testing, which may include an INR done by finger stick or Prothrombin Time (PT) done by venipuncture are performed in our office. These tests are used to assess your blood clotting time and are usually performed monthly to monitor our patients who regularly take anticoagulation drugs such as Coumadin or Warfarin. These drugs are often taken for atrial fib, heart valve replacement, history of blood clots and sometimes after joint replacement surgery.

Spirometry Testing

A Spirometry test, is a test that measures how well your lungs work. This includes how well you’re able to breathe and how effective your lungs are able to bring oxygen to the rest of your body. Spirometry tests can help diagnose illnesses such as Asthma, Allergies, Chronic Bronchitis, Respiratory Infections, Lung Cancer and more.

I love to read my newspaper at the waterfront in Newburyport. I’m traditional. That’s what I like about my doctor and the office and Newburyport Medical Associates. I feel comfortable with them and they help me sustain good health — so I can do the things I love most.

Bob Colomycki

I enjoy photography, especially capturing the beauty of birds in their natural settings. Sometimes I share my work with Newburyport Medical Associates and they take special interest, not only in my passion but in me—that’s a nice feeling.

I love to crochet by the waterfront and just relax with my husband. I can because the Newburyport Medical Associates team is delightful to deal with and they help encourage me to enjoy life with a healthy approach. Having a responsive and friendly doctor’s office is very comforting.

As it is for most people, I realize health is of primary importance. I've been a patient with Newburyport Medical Associates for about 40 years, first with Dr. Mendelson and now with Jane Cleveland. If I have a question, or need an unexpected appointment, I can count on them. This is very reassuring.
